RFID vs Barcodes: A Quick Comparison
Advantages of RFID
RFID technology automates data collection and vastly reduces human effort and error
RFID supports tag reading with no line-of-sight or item-by-item scans required
RFID readers can read multiple RFID tags simultaneously, offering increases in efficiency
All RFID tags within range can be detected instantly and matched with information in your database
Assets can be cross-referenced against assigned locations and recorded as present, missing, or relocated
RFID can be integrated with active scanning and fixed readers for a totally automated tracking solution
Assets and employees can be tracked and located automatically for everything from supply chain and asset management to facility security and emergency planning
Available scanners support both RFID and barcoding so you can upgrade at your own pace
Surpasses Barcodes Limitations
RFID avoids the limitations of barcode scanning, which requires line-of-sight access to each barcode and can only be used to scan one item at a time. Instead, RFID tags do not require line-of-site, and multiple RFID tags can be detected and read remotely and simultaneously. They can be read from a variety of distances based on the type of tag and the use of a handheld reader or a fixed RFID reader combined with an antenna.
This means that, even with entry-level handheld readers, multiple RFID tags can be read simultaneously from a distance 6 to 15 feet, and more advanced tags enable distances of 30 to 50 feet or more for select items. So, rather than having to pick up or turn over a piece of equipment and scan its barcode, a user can simply wave a handheld reader within range of multiple assets tagged with RFID. The device will automatically read and recognize the tags, even if they are located underneath the objects and are not visible. Moreover, fixed readers combined with antennas eliminate the need for handheld reading and provide a fully automated solution for tracking the movement or location of assets and even employees virtually anywhere in your facilities.
Mitigate Human Error
RFID not only streamlines and automates asset scanning but also eliminates the possibility of human error. Each asset or tagged item is detected and identified automatically, and it is matched up with the correct information in your database using its unique ID. There is no possibility of human scanning errors or incorrect logging or updating of information on paper records or in a spreadsheet. This allows manufacturers to maintain a completely accurate inventory of all tagged assets and properly account for current assets and future supply chain, planning, or equipment needs. Plus, with RFID tagging, workers can quickly locate and identify any asset or even track the movement and verify the location of employees anywhere in your buildings.

FAQs
RFID avoids the limitations of barcode scanning, which requires line-of-sight access to each barcode and can only be used to scan one item at a time. Instead, RFID tags do not require line-of-site, and multiple RFID tags can be detected and read remotely and simultaneously.
What are the advantages of RFID vs barcodes? ›
While barcode scanners require a line of sight to scan each code individually, RFID scanners can read multiple codes at once, which can help streamline operations. RFID systems are much more efficient for scanning a large number of items but can be more expensive and require more setup than barcodes.
What are the main advantages of RFID technology over barcode technology in inventory control system? ›
RFID labels allow accurate and real-time tracking of both the quantity and location of products in a warehouse or storage facility. By eliminating the need for human resource to manually count items or scan individual barcodes, RFID streamlines the inventory process, resulting in time, cost, and effort benefits.
What are the advantages of using RFID? ›
RFID technology offers efficiency benefits by automating data capture processes, streamlining operations, and providing real-time visibility. With automatic and rapid data collection, RFID minimizes human intervention, reducing errors and saving time.
What are the main differences between an RFID and an UPC system? ›
Basic RFID can track tags anywhere within 50-100ft of a tag, not in a line of sight, and scan multiple tags simultaneously. More advanced active tags, usually battery operated, can track nearly 500 yards. Compared to UPC which requires the scanner to be in close proximity and in clear line of sight.
Will RFID replace barcodes? ›
Although both RFID and barcodes are both technologies of item identification, they are not a replacement for each other.
What is the disadvantage of using RFID? ›
Disadvantages of RFID:
Some examples of this include: Barcode labels can be very inexpensive (a matter of a few cents per label) whereas RFID tags can run the gamut from $1/tag to upwards of $30/tag, all dependent upon the type of tags you need. RFID readers are also a bit pricier than barcode scanners.
What are two advantages and two disadvantages of using RFID in supply chain management? ›
Integration with Emerging Technologies
| Aspect | Before RFID Integration | After RFID Implementation |
|---|
| Inventory Accuracy | Approx. 74% | Up to 99% |
| Operational Downtime | Frequent | Significantly Reduced |
| Cost of Operations | Higher due to inefficiencies | Reduced by up to 30% |
| Envrionmental Impact | High | Reduced with Sustainable Practices |
Jun 21, 2024
An RFID tag's RSSI value can range anywhere from - 30 to -92 dBm and the closer the RSSI value is to 0, the better the signal.
Why is RFID better? ›
RFID not only streamlines and automates asset scanning but also eliminates the possibility of human error. Each asset or tagged item is detected and identified automatically, and it is matched up with the correct information in your database using its unique ID.
RFID systems offer benefits for businesses of all sizes, allowing them to rapidly improve efficiency and reduce cost by automating processes and improving utilisation of assets and quality. RFID can form the basis of an effective asset management system and is also at the heart of the Internet of Things.
What is the main purpose of RFID? ›
RFID tags are a type of tracking system that uses radio frequency to search, identify, track, and communicate with items and people. Essentially, RFID tags are smart labels that can store a range of information from serial numbers, to a short description, and even pages of data.
What are the advantages of RFID over barcodes? ›
RFID Advantages
Can read RFID tags from a greater distance than barcodes. RFID tags don't need to be positioned in a line of sight with the scanner. RFID tags can be read at a faster rate than barcodes; as approximately 40 RFID tags can be read at the same time.
What are the advantages of using RFID technology instead of bar code scanning technology in managing inventory and direct materials in a manufacturing company? ›
RFID typically offers higher accuracy as it doesn't require visual contact to scan items. Speed is another critical metric, with RFID systems capable of reading multiple tags simultaneously, significantly faster than barcode scanners which must scan each barcode individually.
What is the one most important comparison between RFID and bar codes this year? ›
RFID allows for better automation and more useful data gathering. This helps with planning and quick decision making. Barcodes, however, are not as dynamic and can't track items in real time. Choosing between RFID and barcodes should be based on what your business needs.
What are the advantages of RFID over QR codes? ›
While RFID provides a more automated and real-time tracking system, QR codes are a more cost-effective solution that is easy to implement and use. However, QR codes are more limited in their capabilities and may require manual scanning, making them less efficient for large-scale asset management.
What is one of the main differences between barcodes and RFID barcodes require a direct line of sight to read the? ›
Barcodes use optical signals that have to be read by a scanner and require direct line of sight. RFID (Radio Frequency Identification) uses radio waves to capture data from RFID tags, which do not require a direct line of sight and can be read from a greater distance.
Which of the following is an advantage of bar coding over RFID? ›
Which of the following is an advantage of bar-coding over RFID? (Correct. Bar-coding is currently less expensive than RFID.)
Which technology is more expensive barcode or RFID? ›
RFID technology is generally more expensive than barcode technology. RFID tags can cost $1 to $30, while barcode labels are just a few cents each.
